This new version of Oasys PRIMER includes a number of new features such as:

  • Support for LS-DYNA R8.0 keywords
  • Checking of models, and various other core features are now much quicker.
  • Improved BOM feature, including the ability to write images to a BOM.
  • Redesigned connection creation panel to improve work flow.
  • Bespoke, user defined bolted connections that can be easily applied in multiple locations in the model automatically.
  • Ability to compare connection information across models easily.
  • Exploded view.
  • Deletion added to a number of places, and a general “undo” button has also been added (applies to all deletion).
  • Improvements to Dyna Dummy Positioning:
    • Improved work flow.
    • Better handling of encrypted dummy models.
    • Ability to unlock occupant from H-point during positioning
  • New element quality measures.
  • “Only” button added to all edit panels to allow easier model investigations and visualisation.
  • Reading of JT files has been added.
  • New customisable mouse controls to allow quicker creation of entities.
  • Various pedestrian markup/model build improvements.
  • Made it easier to save settings and preferences from various panels.
  • Added the ability to specify includes ranges for particular entity types.
  • Added various new node selection methods (free edge, nodes round hole).
  • Added ability to reorder include files in the model according to include name.
  • Support for all keywords up to and including LS-DYNA R8.
  • Seatbelt fitting improvements:
    • *PARAMETER created to hold the length of each belt segment after fitting.
    • Make fitting a seatbelt round a child dummy in a seat easier.
    • Mesh belt round a small radius as an alternative to using a slip-ring.
    • General bug fixing.

This new version of Oasys D3PLOT includes a number of new features such as:

Multiple Data Components

  • Multiple components can be plotted simultaneously
  • Different plotting modes can be can be set for each entity type
  • Components can be turned on/off for each entity type

Composite Models

  • It is easier to post-process models with *ELEMENT_SHELL_COMPOSITE
  • Data can be plotted on a per ply basis
  • The local axis (as defined by the beta angle) can be visualised
  • Plys and layups can be blanked/unblanked and viewed in the part tree

Write Menu

  • The output from the WRITE menu is now output to a table
  • Data from up to 10 components can be output at a time
  • The data can be sorted into ascending or descending order by clicking on column headers
  • The data can be written out in text, CSV or XLSX (Excel) format
  • Entities can be (un)blanked/sketched/only'd by right-clicking on the rows in the table
  • The data can be copied to the clipboard and pasted in external programmes

New Data Components

  • Wear Depth and Sliding Distance from the CTF (interface force) file
  • Nodal Normal Velocity from the D3ACS (Acoustic FEM) file
  • Pressure and Sound Pressure from the D3ATV (Acoustic Transfer Vector) file
  • Current Coordinates can be contour plotted. Previously they were only availble in the WRITE and XY_DATA menus

Data Mapping

  • Results from single point elements (Airbag Particles, DES and SPH) can now be contoured over a continuous mesh.
  • D3PLOT creates a cellular mesh around the volume of space occupied by the elements and aggregates data from the elements in each cell into a single values. This is then used as a basis for contouring.
  • It can give a much clearer view of the overall behaviour of the elements.

Changes to Spotwelds

  • Spotweld data can be displayed either on the spotweld entity or the underlying structural elements.
  • By default spotwelds are always drawn and data plotted on them.

New JavaScript functions:

  • GetMultipleData() to extract results for a range of items in a single call
  • GetPlyIntPoint() returns the integration point of a composite ply in a shell
  • GetElemsInPly() returns a list of the elements in a composite ply
  • GetPlysInLayup() returns a list of the composite plys in a composite layup

Miscellaneous additions:

  • An option has been added to the XY DATA menu to set whether to extract data from a frequency domain analysis as magnitude or magnitude * cos(phase + phi)
  • In a D3PLOT-T/HIS link session the current time in D3PLOT can be displayed on a curve created using the COMbine operation as a point.
  • Options have been added to the MEASURE menu to measure the shortest distance from a node to a part and between two parts.
  • An option has been added to exclude parts being blanked by cut-sections.
  • Individual files (family members) can now be any size up to 9 Exawords.

This new version of Oasys T/HIS includes a number of new features such as:

  • ATAN2 Math Operation JavaScript ATAN2 Function
  • Added Triaxiality Factor component for Solids, Shells and Thick Shells
  • Fast-TCF datum command to remove a datume line from graphs
  • Fast-TCF command to set a user defined model prefix
  • Fast-TCF command to add parts to a part group
  • Added support for reading curves written to the CURVOUT_ASCII file
  • Added support for reading the Multi-Physics Database ASCII files: ICFD_NODOUT, ICFD_POINTOUT, CESE_ELOUT, CESE_POINTOUT, EM_ELOUT, EM_NODOUT, EM_POINTOUT
  • Added Airbag LSDA data components Translational KE, Inflator Energy and Heat Convection Energy
  • Added CPM Sensor ASCII data component N Particles
